JUST NOW YOU CAN NOT BUY IT (OUT OF STOCK). PLEASE RETURN THIS ITEM BACK FOR SALE. IT IS VERY MUCH MISSED .THANK YOU Review: Ideal item for your aquarium, shrimp safe. - Excellent product, use these all the time, slowly dissolve (or slowly get eaten if you have plecs and shrimp) releasing food/minerals to the water. The mini ones last 4-7 days in my 19l tanks (with shrimp, cory and 3 betta), and about 3 days in my community tanks. Don't use too many though as you will see a rise in your water TDS, I now put one in every other week. This is very shrimp friendly, out of all my tank inhabitants, the cherry and amano shrimp spend hours grazing on the blocks. ## Features - Contains 15+ Essential Vitamins and Minerals in a Paletable, Slow Releasing Block - Boosts Aquarium Bioavailable Calcium and Minerals - Added Health for Tropical Fish Breeding and Fry - Calcium and Essential Minerals for Shrimp Breeding and Shedding - 100% Invertebrate and Plant SAFE! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01HU7RV6Q | | Batteries Included | No | | Batteries required | No | | Breed Recommendation | All Breed Sizes | | Customer Reviews | 4.8 4.8 out of 5 stars (11) | | Date First Available | 30 Jun. 2016 | | Flavor | Fish | | Item Weight | 4 g | | Manufacturer reference | MI | | Number of Items | 25 | | Pet Life Stage | All Life Stages | | Quantity | 1 | | Size | 25 Blocks | | Storage Information | Keep Dry | ## Product Details - **Brand:** AQUALIBRA UK - **Item weight:** 4 Grams - **Manufacturer:** Aqualibra UK ## Images ![25 x CALCIUM & MINERAL BLOCKS (MINI 4g) for Tropical FISH, INVERTEBRATES and REPTILES - Image 1](https://m.media-amazon.com/images/I/71vsI3SmcsL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ BEST CUBES I EVER HAD *by G***A on 15 January 2023* BEST CUBES MY SHRIMPS ARE LOVING IT.
